IMPROVEMENT IN NUT AND BOLT FASTENINGS.

f Specification formingpart of Letters Patent No. 133,8723fdated December 10, 187.

To all whom 'it may concern:

Be it known that I, MALcoLM F. MCINTYEE, of Girard, in the county of Erie and State of Pennsylvania, have invented a new and useful Improved Nut-Lock; and I do hereby declare that the following is a full, clear, and eX- act description thereof sufficient to enable those skilled in the art to which my invention appertains to make and use the same, reference being hadto the accompanying drawing making part 'of this spccilication, and to the letters and figures marked thereon.

The nature of my invention consists in the peculiar construction of the nut-locking device, and its arrangement and combination with the nut and the fish plate or other article through which the bolt passes.

In the drawing, Figure l is a longitudinal section of the fishplate 5 Fig. 2 is a longitudinal section of the sh-plate and rail, together with the bolt, nut, and locking device; and Fig. 3 is a perspective view, showing the nut secured in position.

A represents an ordinary screw-bolt, and B `an angular nut. Fis a fish-plate, perforated to'allow the bolt to pass through. On one side of the perforation is a notch or depres-b sion, c1, which is continued along the outer face of the sh-plate, as shown at c2, a sufficient distance to allow the rod D to be turned down. D'represents a piece of wire, of such length and thickness as to correspond with the size 0f the nut, bolt, and fish-plate, and furnish sufficient strength for the purpose required.

The wire is straight when first applied, and afterward bent, as. follows: The fish-plate is placed over the bolt and the wire is inserted in the notch or depression c1, and then bent at a right angle, so as to occupy the depression c. The nut is then placed on the end of the bolt and screwed home, and the Wire again bent at a right angle until it is in contact with the nut,'as shown, thus effectually-preventing the nut from turning.

I claim as f new and'desire to secure by Letters Patent- The fish-plate F, having the recessesc1 c2,

in combination with the bolt A, nut B, and bent wire D, as shown and described.

The above specification of my invention signed by me this 31st day of July,1872.
